Simplex Trading reduced its stake in Nio by 38.95% in the fourth quarter, while sharply cutting its options positions in the Chinese premium EV maker, according to a regulatory filing published Wednesday.
Nio‘s US-listed shares peaked at $66.99 in January 2021 as the company’s founder and CEO unveiled the first model of the second-generation vehicle platform while teasing the expansion to the US before the end of 2025.
The rally, which also lifted Chinese rivals XPeng and Li Auto to record highs, came amid an EV bubble that briefly pushed newly public Rivian and Lucid past Ford and General Motors in market value.
None of the six NEV startups has approached those peaks in the last five years, while Tesla hit a fresh all-time high last December.
Simplex x Nio
Simplex held 659,692 Nio shares valued at $3.36 million as of December 31, down from approximately 1.08 million shares at the end of September.
The market maker had nearly doubled its stake in the third quarter of the year after having dumped nearly all shares exactly a year ago.
The third quarter of 2023 marked the ownership peak with nearly 2 million shares.
The Chicago-based firm also slashed its call options by 3.58% to 9,741,900 contracts worth $49.68 million, and cut its put options by 36.6% to 4,383,000 contracts valued at $22.35 million.
The reductions came as Nio shares fell 34% in the fourth quarter, closing at $5.04 on December 31 compared with $7.62 on September 30.
